通过数值计算和物理模拟两方面发现，在不使用外加动力的情况下，利用钢包内钢液面位置势能的弯水口注流可以在离心室内产生相当强度的旋流。
Besides the stirring forces, the swirling strength may be reinforced by using bending nozzle, which use the height potential energy of molten steel in ladle.
结论：缺氧性肺动脉高压大鼠右心室早期表现为离心性肥大。
Conclusion : Eccentric hypertrophy accounts for the early change of right ventricle in hypoxic pulmonary hypertension rats.
